For the second Saturday in a row, ESPN’s College GameDay show will air from the site of a Big 12 game — this time, at Iowa State for the annual Cy-Hawk rivalry.

Iowa State is hosting No. 18 Iowa, and this will be a chance for Matt Campbell's program to validate its preseason hype in a game with the national spotlight on it.

This is also one of six Big 12 games that pair teams from Power Five conferences, and one of two battles this week between the Big 12 and Big Ten.

But this cross-conference matchup is nothing like last Saturday’s LSU at Texas slugfest, however.

So here we go, entering Week 3:

No. 1 Oklahoma (2-0)

Last week’s ranking: 1

Most recent result: Throttled South Dakota 70-14.

In a nutshell: When will quarterback Jalen Hurts play a full game? It might be a while longer, although the Alabama transfer is putting up good numbers despite essentially being a part-timer. While leading the Sooners to 2-0, he’s 34-of-41 for 591 yards, with six touchdowns and no interceptions. He could have another big day Saturday, too, considering the Bruins are 0-2 for the second season in a row.

On deck: at UCLA, 8 p.m. ET Saturday on FOX.

No. 2 Texas (1-1)

Last week’s ranking: 2

Most recent result: Lost at home against Top 10 LSU 45-38.

In a nutshell: Sam Ehlinger, for a change, wasn’t the best quarterback on the field last Saturday. Not that he was bad, it’s just that the Longhorn slinger found himself in a rare undercard role to LSU’s Joe Burrow, whose talented receivers had their way against what’s still a solid Longhorn secondary.

No. 3 Iowa State (1-0)

Last week’s ranking: 3

Most recent result: Did not play last week. Opened season with 29-26 three-overtime win against Northern Iowa.

In a nutshell: A banged-up Iowa State offense had a bye week in which the starting center and the most versatile back rested injuries. They’ll face an Iowa defense that held Big Ten also-ran Rutgers to only five first down and 125 yards of offense.

On deck: vs. Iowa at 4 p.m. (ET) Saturday on FS1.

No. 4 Oklahoma State (2-0)

Last week’s ranking: 4

Most recent result: Overwhelmed McNeese State 56-14.

In a nutshell: Hawaii transfer quarterback Dru Brown got much-needed playing time, entering the game with 11 minutes left in the third quarter. He completed 7 of 10 passes for 142 yards and two touchdowns, but more important, bolstered confidence after redshirt freshman Spencer Sanders got the starting job.

On deck: at Tulsa, 3:30 p.m. (ET) Saturday on ESPN2.

No. 5 TCU (1-0)

Last week’s ranking: 5

Most recent result: Did not play last week. Opened season with 39-7 victory against Arkansas-Pine Bluff.

In a nutshell: Winning on Saturday would be a nice first step in proving that TCU football is back, after what was by Horned Frogs standards a disappointing 7-6 overall record that included going 4-5 in the Big 12. Which Purdue shows up, the one that lost 34-31 against Nevada, or the one that beat Vanderbilt 42-24?

On deck: at Purdue, 7:30 p.m. (ET) on Big Ten Network.

No. 6 Baylor (2-0)

Last week’s ranking: 6

Most recent result: Beat Texas-San Antonio 63-14.

In a nutshell: The Bears get a Saturday off, after overwhelming a pair of lower-level State of Texas opponents by a combined 119-31. Quarterback Charlie Brewer enters the bye week without having played much more than a half against either Stephen F. Austin and UTSA.

No. 7 Kansas State (2-0)

Last week’s ranking: 9

Most recent result: Shellacked Bowling Green 52-0.

In a nutshell: When’s the last time Kansas State started a season with 500-plus yards during a season’s first two games? Never. That’s the bar new coach Chris Klieman has set, after his Wildcats backed up a 573-yard effort in the opener against Nicholls, with 521 yards last Saturday. Adding to the streak on the road this weekend will be a chore.

Up next: at Mississippi State, noon (ET) on ESPN.

No. 8 Texas Tech (2-0)

Last week’s ranking: 7

Most recent result: Beat Texas-EL Paso 38-3.

In a nutshell: There’s carping in Lubbock about quarterback Alan Bowman’s performance, after going 30 of 45 for 260 yards and three touchdowns. On a day when Army won at Michigan — any victory should be welcomed, and especially when players are learning a new system.

Up next: at Arizona, 10:30 p.m. (ET) on ESPN.

No. 9 West Virginia (1-1)

Last week’s ranking: 8

Most recent result: Lost at Missouri 38-7.

In a nutshell: Coming off its worst defeat since 55-14 against Kansas State in 2012, the Mountaineers try to regroup against another Power 5 opponent. And get this: West Virginia has just 64 rushing yards on 56 carries in two games.

Up next: vs. North Carolina State, noon (ET) on FS1.

No. 10 Kansas (1-1)

Last week’s ranking: 10

Most recent ranking: Lost against Coastal Carolina 12-7.

In a nutshell: Any chance that Kansas will immediately narrow the differential between Jayhawks and state-rival Kansas State — put that thought on hold. It still could take a while.
